MailScanner cloud image, best practice?

[Remco Barendse]

Hi list

I would like to build an image of CentOS 7 and MailScanner for quick and 
rapid deployment in a cloud environment, 3 cloud instances will be 
checking mail.

As basis i am thinking to take CentOS 7 Generic cloud image but the 
storage space in the issue is fairly limited, like 8Gb disk size.

How to deal with storage space? I have to keep archive copies of all 
email going in and out, should i do an NFS mount for
/var/spool/MailScanner/archive
and
/var/spool/MailScanner/quarantine

But if the NFS mount would fail at boot time, the small storage space of 
the cloud image will fill up instantly.


Are there any other caveats?

Thanks for any tips / hints!
Remco
